The Murasakino Musique Analogue ‘Sumile’ MC Phonograph Cartridge Makes Me Smile!


The Murasakino Musique Analogue ‘Sumile’ MC phonograph cartridge makes me smile while I'm listening to music! The Sumile reminds me of the exotic Lefson Ultra resistors from France, and like the Ultra's, the Sumile is astonishingly transparent & resolving, while being rich, natural, and exceedingly musical at the same time - a very nice magic trick! With the wirewound resistors... Read More »

Hacked! Decision point - is this the end of Jeff's Place? Updated.


I don't know how many of you stopped by Jeff's Place on April 5th to do a little reading, but depending on when you stopped by, you might have noticed that nothing came up but a white screen. That's because somebody decided it would be fun to hack Jeff's Place and destroy it. Apparently, somebody (or a malware... Read More »


A Shielded Duelund DCA20GA Interconnect for the Weekend! Updates!


I've been wanting to try the Duelund DCA20GA tinned-copper tone-wire as a shielded interconnect between my Intact Audio SUT and vintage McIntosh MX110Z tuner-preamplifier for a while now.

A Complete Duelund DCA Rewire of the Westminster Royal SE's Crossovers!


Yesterday after I rewired the high-frequency circuits of my Westminster's Duelund CAST crossovers with the Duelund DCA20GA tinned-copper tone wire, I was so excited by the results that I decided I wanted to rewire the low-frequency circuits too. It was spur of the moment decision to rewire my crossovers, so I didn't precondition any of the... Read More »


Jeff Checking In: Duelund DCA20GA Tinned-Copper Tone Wire, and Other Stuff.
